Answer:
D: two jaguars per thousand hectares.
Explanation:
Population density refers to the computation of population by unit area. It is usually implemented in living organisms, generally in humans. It is a key geological term. In easy form, population density implies to the number of people existing in an area per square kilometer or hectare, etc.
So, two jaguars per thousand hectares is an example of population density as it involves the number of jaguars (population) per thousand hectares (per unit area).
Answer:
Living organism contains both the organic and inorganic molecules in their body. Inorganic molecules are present as trace elements in their body and plays an important role in growth and metabolism of the organism.
Iodine is an important trace element of the body. One should include ionized salt in its diet as iodine acts as a precursor of thyroxine hormone. The deficiency of iodine in the body can cause a disease known as goiter. Iodine plays an important role in the growth and metabolism of an individual.
Answer:
homeostasis
Explanation:
An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.
Basically, the endocrine system contributes significantly to the state of homeostasis in the body.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment ideal to enhance life and proper functionality.
For example, if a person becomes infected with a pathogen such as a virus. The internal stimulus that most likely takes place in order for their body to maintain homeostasis is that their core temperature increases. This is simply because pathogens such as a virus do not thrive or survive in a hot environment; they're naturally allergic to high temperature (heat).
In conclusion, homeostasis is the term used to describe the maintenance of a constant internal environment or balance by living organisms such as humans and animals.
